Lucy Heartfilia is the primary female protagonist of Fairy Tail. She is a 17-year-old celestial wizard who uses a set of magical Gatekeys to summon celestial spirits. She also fights with a whip, which she upgrades to the extendable energy whip Fleuve d'Étoiles. At the age of 16, Lucy flees from her home to pursue her dream of joining Fairy Tail. Her efforts lead into conflict with a slave trader named Bora, and Natsu Dragneel and Happy rescue her in exchange for her joining Fairy Tail. She performs guild-posted jobs alongside Natsu and Happy to fund her rented house in Magnolia, and is bewildered by her guildmates' antics.
